FIELD

The present invention relates generally to the field of programmablecontrollers for homes and/or buildings and their related grounds. Morespecifically, the present invention relates to simplified interfaces forsuch controllers having interview programming capabilities.

BACKGROUND

Controllers are used on a wide variety of devices and systems forcontrolling various functions in homes and/or buildings and theirrelated grounds. Some controllers have schedule programming thatmodifies device parameter set points as a function of date and/or time.Some such device or system controllers that utilize schedule programmingfor controlling various functions in homes and/or buildings and theirrelated grounds include, for example, HVAC controllers, water heatercontrollers, water softener controllers, security system controllers,lawn sprinkler controllers, and lighting system controllers.

HVAC controllers, for example, are employed to monitor and, ifnecessary, control various environmental conditions within a home,office, or other enclosed space. Such devices are useful, for example,in regulating any number of environmental conditions with a particularspace including for example, temperature, humidity, venting, airquality, etc. The controller may include a microprocessor that interactswith other components in the system. For example, in many modernthermostats for use in the home, a controller unit equipped withtemperature and humidity sensing capabilities may be provided tointeract with a heater, blower, flue vent, air compressor, humidifierand/or other components, to control the temperature and humidity levelsat various locations within the home. A sensor located within thecontroller unit and/or one or more remote sensors may be employed tosense when the temperature or humidity reaches a certain thresholdlevel, causing the controller unit to send a signal to activate ordeactivate one or more components in the system.

The controller may be equipped with an interface that allows the user tomonitor and adjust the environmental conditions at one or more locationswithin the building. With more modern designs, the interface typicallyincludes a liquid crystal display (LCD) panel inset within a housingthat contains the microprocessor as well as other components of thecontroller. In some designs, the interface may permit the user toprogram the controller to activate on a certain schedule determined bythe user. For example, the interface may include a separate menu routinethat permits the user to change the temperature at one or more timesduring a particular day. Once the settings for that day have beenprogrammed, the user can then repeat the process to change the settingsfor the other remaining days.

With more modern designs, the programmable controller may include afeature that allows the user to set a separate schedule for weekday andweekend use, or to copy the settings for a particular day and then applythem towards other selected days of the week. While these designs allowthe user to copy settings from one day to another, a number of steps areoften required to establish a program, adding to the complexity of theinterface. In some cases, the interface may not permit the user toselect multiple days outside of the normal weekday/weekend scheme. Inother cases, the interface is simply too complex to be conveniently usedto program a temperature scheme and is simply by-passed or notprogrammed by the user. Accordingly, there is an ongoing need in the artto decrease the time and complexity associated with programming amulti-day schedule in a programmable controller.

During the installation process, the steps required to program thecontroller to operate with other system components can also add to thetime and complexity associated with configuring the controller.Typically, programming of the controller is accomplished by entering innumeric codes via a fixed segment user interface, by manually settingjumper switches on a circuit board, or by adjusting screws orpotentiometers on a circuit board. In some cases, the codes or settingsused to program the controller are obtained from a manual or table whichmust be consulted by the installer during the installation process. Forexample, to configure an HVAC system having a multistage heat pump, thecontroller may require the installer to enter a numeric or alphanumericcode (e.g. 91199) from a manual or table in order to program thecontroller to properly operate the various stages of the heat pump. Suchprocess of referring to a manual or table of codes is not oftenintuitive to the user, and requires the user to store the manual in asafe place for subsequent use. Accordingly, there is also an ongoingneed in the art to decrease the time and complexity associated withprogramming the controller during the installation process.

SUMMARY

Generally, the present invention pertains to simplified interfaces forcontrollers having interview programming capabilities.

In one illustrative embodiment, a method of programming a schedule of acontroller having a user interface is described. The illustrative methodincludes the steps of providing one or more interview questions to auser via the user interface; accepting one or more user responses to theone or more interview questions from the user via the user interface;and creating and/or modifying or building a schedule based on the userresponses.

In another illustrative embodiment, a method of programmingconfiguration information within a controller is further described. Anillustrative method can include the steps of providing one or moreinterview questions to a user via a user interface, prompting the userto selected between at least two answers simultaneously displayed on theuser interface, accepting one or more user responses to the interviewquestions via the user interface, and modifying the operationalparameters of the controller and/or one or more components controlled bythe controlled based at least in part on the user responses. Theinterview questions can include at least one question relating to theinstallation or setup of the controller as well as any componentscontrolled by the controller.

An illustrative controller having interview programming capabilities caninclude an interview question generator adapted to generate a number ofinterview questions relating to the installation or setup of thecontroller and/or any components controlled by the controller, a userinterface including a display screen adapted to display interviewquestions to a user along with at least two answers for each interviewquestion, and a memory unit for storing operational parameters withinthe controller based at least in part on the user responses to theinterview questions.

DETAILED DESCRIPTION

The following description should be read with reference to the drawings,in which like elements in different drawings are numbered in likefashion. The drawings, which are not necessarily to scale, depictselected embodiments and are not intended to limit the scope of theinvention. Although examples of construction, dimensions, and materialsare illustrated for the various elements, those skilled in the art willrecognize that many of the examples provided have suitable alternativesthat may be utilized.

Generally, the present invention pertains to simplified interfaces forcontrollers having interview programming capabilities. These controllerscan be used in a variety of systems such as, for example, HVAC systems,water heater systems, water softener systems, sprinkler systems,security systems, lighting systems, and the like. The Figures depictHVAC controllers. While the present invention is not so limited, anappreciation of various aspects of the invention will be gained througha discussion of the examples provided below.

FIG. 1 is a flow diagram of an illustrative HVAC interview program 100.The flow diagram starts at a normal thermostat operation block 110.Normal thermostat operation block 110 can be an initial parametersetting operation or a modification of parameter settings. Interviewscheduling block 120, 130 provides one or more interview questions to auser via the user interface. The user interface can accept one or moreresponses to the one or more interview questions from the user via theuser interface. The schedule is then built or modified, in some cases byadding or modifying one or more schedule parameters 140, 150, based onthe user responses provided via the user interface. Once the scheduleparameters 140, 150 are modified, the controller can return to thenormal operation block 110, and follow the new schedule.

In some embodiments, the interview scheduling blocks 120 and 130 canprovide interview questions that elicit an affirmative (e.g., “yes”) ornegative (e.g., “no”) user response. Alternatively, or in addition, theinterview scheduling blocks 120, and 130 can provide include interviewquestions that allow a user to select one (or more) answers from apredetermined list of answers.

In some embodiments, these interview questions can solicit informationfrom the user regarding the grouping of the controller set pointsentered or the temporal relationship of the controller set points suchas, for example, the interview question may ask “Do you want theschedule to apply to every day of the week?”, requiring the user torespond with a “YES” or “NO” answer. The interview scheduling block 120preferably includes questions that are natural language questions, whichmay be phrases that have one, two, three, four, five, six, or seven ormore words, although this is not required in all embodiments.

Alternatively, or in addition, interview scheduling block 130 canprovide interview questions that require a numerical user response. Forexample, these interview questions can solicit information from the userregarding the specific time and temperature set points for each groupingof controller set points solicited by the interview block 120 describedabove. Interview block 130 can provide a question such as, for example,“What is a comfortable sleeping temperature in the winter?”, requiringthe user to respond with a numerical temperature answer. Like interviewschedule block 120 above, interview scheduling block 130 can includequestions that are natural language questions, which may be phrases thathave one, two, three, four, five, six, or seven or more words, althoughthis is not required in all embodiments.

The interview scheduling blocks 120 and 130 can provide one or moreinterview questions about, for example, which weekdays will have thesame schedule?, when a first person wakes up?, when a last person goesto sleep?, when a last person leaves during the day?, when a firstperson arrives home?, what a comfortable temperature is when heat ison?, what a comfortable temperature is when air conditioning is on?,what a comfortable sleeping temperature is in summer?, and/or what acomfortable sleeping temperature is in winter?

Alternatively, or in addition, the interview scheduling blocks 120 and130 may provide one or more interview questions that provide a pluralityof predetermined answers or responses (e.g., multiple choice format)where the user selects an answer or response. For example, the interviewquestion may provide a question such as, “What type of schedule do youdesire?” In this illustrative embodiment, a series of predeterminedresponses or answers can be provided such as, “Every day of the week isthe same,” “Weekdays are the same and Saturday/Sunday is the same,”“Weekday are the same and Saturday/Sunday is different,” “Each Weekdayis different and Saturday/Sunday is the same,” and “Each day of the weekis different.”

Alternatively, or in addition, once an initial schedule has been built,the interview scheduling blocks 120, and 130 can display a previousanswer that was accepted by the user interface based on the prior builtschedule. This illustrative feature can provide the user with aconvenient option to select and alter only the schedule parameters 140,150 that the user desires to modify. This feature can be utilized in allillustrative embodiments described herein, however it is not required.

FIG. 2 is a block diagram of the illustrative HVAC controller with anillustrative interview function similar to that shown in FIG. 1.Controller 200 includes a control module 210 that can be amicroprocessor or the like. The control module 210 communicates with auser interface 220, and can include an interview question generator 225,a response acceptor 240 and a programmable schedule 250. The controlmodule 210 can also generate a control signal 260 to a device (notshown), such as an HVAC system or device.

In an illustrative embodiment, the interview question generator 225provides interview questions, such as those described above, to the userinterface 220. The user interface 220 can be any form of user interfacesuch as, for example, a physical interface including a touchscreen, anLCD with buttons, and/or an aural interface including a speaker andmicrophone, or any other suitable user interface. A user can activatethe interview question generator 225 by any suitable mechanism, such asby pressing a schedule button on a touchscreen of the user interface220. Alternatively, or in addition, the controller 210 may activate theinterview question generator 225 on its own, such as when it believesadditional scheduling information is needed or might otherwise bedesired. In response to questions posed by the interview questiongenerator 225, the user can enter one or more user responses into theuser interface 220. The response acceptor 240 accepts the user responsesand provides the response to the programmable schedule 250. In someembodiments, the programmable schedule 250 has a number of time andtemperature set points that can be entered or modified by the responseacceptor 240. Once the schedule is built and/or modified, a controlsignal 260 is generated by the control module 210 based on theprogrammable schedule 250.

FIG. 3 is a flow diagram of another illustrative HVAC interview program300. The flow diagram starts at a normal thermostat operation block 310.Normal thermostat operation block 310 can be an initial parametersetting operation or a modification of parameter settings. Interviewscheduling block 325 provides one or more interview questions to a uservia a user interface. The user interface then accepts one or moreresponses to the one or more interview questions from the user via theuser interface. A user response translator 360 translates the one ormore user responses to form a translated response. One or more scheduleparameters 370 are then modified based on the translated responses fromthe response translator 360. Once the schedule parameters 370 aremodified, the controller can return to the normal operation block 310.

In some embodiments, the interview scheduling block 325 includesinterview questions that require an affirmative (e.g., “yes”) ornegative (e.g., “no”) user response. In addition, the interviewquestions can solicit information from the user regarding the groupingof the controller set points entered or the temporal relationship of thecontroller set points. For example, the interview question may ask “Doyou want the schedule to apply to every day of the week?”, requiring theuser to respond with a “YES” or “NO” answer. The interview schedulingblock 325 can include questions that are natural language questions suchas, for example, phrases that can have one, two, three, four, five, six,or seven or more words.

In an illustrative embodiment, interview scheduling block 325 may alsoprovide interview questions that require a numerical user response.These interview questions can solicit information from the userregarding the specific time and temperature set points for each groupingof controller set points solicited by the interview block 325 describedabove. The interview block 325 can provide a question such as, forexample, “What is a comfortable sleeping temperature in the winter?”,requiring the user to respond with a numerical temperature answer. Theinterview scheduling block 325 can include questions that are naturallanguage questions such as, for example, phrases that can have one, two,three, four, five, six, or seven or more words.

In the illustrative embodiment, the interview scheduling block 325 canalso provide one or more interview questions related to, for example,which weekdays will have the same schedule?, when a first person wakesup?, when a last person goes to sleep?, when a last person leaves duringthe day?, when a first person arrives home?, what a comfortabletemperature is when heat is on?, what a comfortable temperature is whenair conditioning is on?, what a comfortable sleeping temperature is inthe summer?, or what a comfortable sleeping temperature is in thewinter?

The response translator 360 can translate the user responses to createappropriate schedule parameters 370 that help define the schedule of thecontroller. That is, the response translator 360 applies the userresponses to one or more interview questions to establish the controllerschedule. For example, the response translator 360 can take anaffirmative user response to the interview question, “Do you want thesame schedule for Saturday and Sunday?” and correlate with the interviewquestion, “What temperature do you like when the heat is on?” toestablish the schedule parameters for the heating temperature during atleast selected periods on Saturday and Sunday.

Alternatively, or in addition, the interview scheduling block 325 mayprovide one or more interview questions that provide a plurality ofpredetermined answers or responses (e.g., multiple choice format) wherethe user selects an answer or response. For example, the interviewquestion may provide a question such as, “What type of schedule do youdesire?” In this illustrative embodiment, a series of predeterminedresponses or answers can be provided such as, “Every day of the week isthe same,” “Weekdays are the same and Saturday/Sunday is the same,”“Weekday are the same and Saturday/Sunday is different,” “Each Weekdayis different and Saturday/Sunday is the same,” and “Each day of the weekis different.”

FIG. 4A is a block diagram of the illustrative HVAC controller with anillustrative interview function similar to that shown in FIG. 3.Controller 400 includes a control module 410 that can be amicroprocessor or the like. The control module 410 communicates with auser interface 420, and may include an interview question generator 425,a response acceptor 440, a response translator 460, and a programmableschedule 470. The control module 410 can also generate a control signal465 to a device (not shown), such as an HVAC system or device.

In the illustrative embodiment, the interview question generator 435provides interview questions, such as those described above, to the userinterface 420. The user interface 420 can be any form of user interfacesuch as, for example, a physical interface including a touchscreen, anLCD with buttons, and/or an aural interface including a speaker andmicrophone, or any other suitable user interface. A user can activatethe interview question generator 435 by any suitable mechanism, such asby pressing a mechanical schedule button on the controller, touching anappropriate region of a touchscreen, voice activation, etc.Alternatively, or in addition, the controller 410 may activate theinterview question generator 425 on its own, such as when it believesadditional scheduling information is needed or might otherwise bedesired. In response to questions posed by the interview questiongenerator 425, the user can enter one or more user responses into theuser interface 420. The response acceptor 440 accepts the user responsesand provides the response to the response translator 460. The responsetranslator 460 provides a translated response to a programmable schedule470. In some embodiments, the programmable schedule 470 has a number oftime and temperature set points that can be entered or modified by theresponse translator 470. Once the schedule is built and/or modified acontrol signal 465 is generated by the control module 410 based on theprogrammable schedule 470.

FIG. 4B is an illustrative partial block diagram of the block diagramshown in FIG. 4A showing one embodiment of the interaction of theinterview question generator 425, response acceptor 440, responsetranslator 460 and programmable schedule 470. The illustrativeprogrammable schedule 470 has a plurality of cells such as, for example,a Saturday wake cell 471, a Sunday wake cell 472, a Saturday sleep cell473, and a Sunday sleep cell 474. In this embodiment, each cell 471,472, 473, 474 may include a number of schedule parameters such as, forexample, a start time, a heat temperature and a cool temperature.

Interview questions 425 are posed to the user. As shown in theillustrative example: an interview question 425 of “Same schedule forSaturday and Sunday?” elicits an user response 440 of “YES”; aninterview question 425 of “For the weekend, is someone home all day?”elicits an user response 440 of “YES”; an interview question 425 of“What time does the first person wake up?” elicits an user response 440of “7:00 a.m.”; an interview question 425 of “What time does the lastperson go to sleep?” elicits an user response 440 of “10:00 p.m.”; aninterview question 425 of “What temperature is comfortable when the heatis on?” elicits an user response 440 of “72° F.”; an interview question425 of “What temperature is comfortable when the air conditioning ison?” elicits an user response 440 of “68° F.”; an interview question 425of “What is a comfortable sleeping temperature in summer?” elicits anuser response 440 of “67° F.”; and an interview question 425 of “What isa comfortable sleeping temperature in winter?” elicits an user response440 of “65° F.”.

In the illustrative embodiment, the response translator 460 accepts theuser responses provided in block 440. The response translator 460 thenbuilds and/or modifies the programmable schedule 470. In theillustrative embodiment, each cell 471, 472, 473, 474 includes a starttime, a heat temperature and a cool temperature. The Saturday wake cell471 and the Sunday wake cell 472 has a start time of 7:00 a.m., a heattemperature of 72° F., and a cool temperature of 68° F., all of thetimes and temperatures are provided by the response translator. TheSaturday sleep cell 473 and the Sunday sleep cell 474 has a start timeof 10:00 p.m., a heat temperature of 65° F., and a cool temperature of67° F., all of the times and temperatures are provided by the responsetranslator.

In this illustrative embodiment, the response translator 460 takes aplurality of user responses 440 to the interview questions 425 andbuilds and/or modifies a plurality of schedule parameters. The Saturdayand Sunday Leave and Return cells 475, 476, 477, and 478 are ignoredand/or zeroed out by the response translator 460 since they are notrequired based on the user responses 425 for this example.

FIG. 5 is a flow diagram of another illustrative HVAC interview program500. The flow diagram starts at a normal thermostat operation block 510.Normal thermostat operation block 510 can be an initial parametersetting operation or a modification of parameter settings. Interviewscheduling block 525 provides one or more interview questions to a uservia a user interface. The user interface then accepts one or moreresponses to the one or more interview questions from the user via theuser interface. A sufficient information block 560 determines if enoughinformation has been solicited from the user response to the interviewquestions sufficient to build or modify the schedule at block 570. Ifnot, the interview scheduling block 525 provides another interviewquestion to the user via the user interface. If the sufficientinformation block 560 determines that enough information has beensolicited, then the schedule is built or modified by the modify scheduleblock 570. Once the schedule is built or modified by the modify scheduleblock 570, the controller can return to the normal operation block 510.

The sufficient information block 560 can, for example, help ensure thata sufficient number of schedule parameters are defined, such as, forexample, a start time, a heating temperature and a cooling temperaturefor a particular time period such as, for example, a specific day orgroup of days wake period, leave period, return period and/or sleepperiod, as shown in FIG. 4B.

In some embodiments, the interview scheduling block 525 provides anumber of predetermined interview questions in a predeterminedsequential order. The number of questions or queries may be adapted tocollect information from the user responses to generate at least aportion of the schedule parameters.

Like above, the interview scheduling block 525 can include interviewquestions that require an affirmative (e.g., “yes”) or negative (e.g.,“no”) user response. For example, interview scheduling block 525 canprovide interview questions solicit information from the user regardingthe grouping of the controller set points entered or the temporalrelationship of the controller set points such as, for example, “Do youwant the schedule to apply to every day of the week?”, requiring theuser to respond with a “YES” or “NO” answer. The interview schedulingblock 525 can include questions that are natural language questionswhich can be phrases that have one, two, three, four, five, six, orseven or more words in length.

Alternatively or in addition, interview scheduling block 525 can provideinterview questions that require a numerical user response. For example,these interview questions can solicit information from the userregarding the specific time and temperature set points for each groupingof controller set points solicited by the interview block 525 describedabove. The interview block 525 can provide a question such as, forexample, “What is a comfortable sleeping temperature in the winter?”,requiring the user to respond with a numerical temperature answer.Again, the interview scheduling block 525 can include questions that arenatural language questions that can be phrases which can be one, two,three, four, five, six, seven or more words, although this is notrequired in all embodiments.

The interview scheduling block 525 may also provide one or moreinterview questions about, which weekdays will have a same schedule?,when a first person wakes up?, when a last person goes to sleep?, when alast person leaves during the day?, when a first person arrives home?,what a comfortable temperature is when heat is on?, what a comfortabletemperature is when air conditioning is on?, what a comfortable sleepingtemperature is in the summer?, or what a comfortable sleepingtemperature is in the winter?

Alternatively, or in addition, the interview scheduling block 525 mayprovide one or more interview questions that provide a plurality ofpredetermined answers or responses (e.g., multiple choice format) wherethe user selects an answer or response. For example, the interviewquestion may provide a question such as, “What type of schedule do youdesire?” In this illustrative embodiment, a series of predeterminedresponses or answers can be provided such as, “Every day of the week isthe same,” “Weekdays are the same and Saturday/Sunday is the same,”“Weekday are the same and Saturday/Sunday is different,” “Each Weekdayis different and Saturday/Sunday is the same,” and “Each day of the weekis different.”

FIG. 6 is a block diagram of the illustrative HVAC controller with anillustrative interview function similar to that shown in FIG. 5.Controller 600 includes a control module 610 that can be amicroprocessor or the like. The control module 610 communicates with auser interface 620, and may include an interview question generator 625,a response acceptor 640 and a programmable schedule 650. The controlmodule 610 can also generate a control signal 660 to a device (notshown), such as an HVAC system or device.

In the illustrative embodiment, the interview question generator 625provides interview questions, such as those described above, to the userinterface 620. The user interface 620 can be any form of user interfacesuch as, for example, a physical interface including a touchscreen, anLCD with buttons, an aural interface including a speaker and microphone,or any other suitable user interface. A user can activate the interviewquestion generator 625 by any suitable mechanism, such as by pressing aschedule button on a touchscreen of the user interface 620.Alternatively, or in addition, the controller 610 may activate theinterview question generator 625 on its own, such as when it believesadditional scheduling information is needed or might otherwise bedesired. In response to the questions posed by the interview questiongenerator 625, the user can enter one or more user responses into theuser interface 620. The response acceptor 640 accepts the user responsesand provides the responses to the programmable schedule 650 if itdetermines that sufficient information has been provided by the userresponses to establish a program schedule. If not, the response acceptor640 instructs the interview question generator 625 to provide anotherinterview question to the user via the user interface 620. Once theresponse acceptor 640 determines that sufficient information has beenprovided by the user to establish a program schedule 650 the programschedule 650 is built and/or modified. In some embodiments, theprogrammable schedule 650 has a number of time and temperature setpoints that can be entered or modified by the response acceptor 640.Once the programmable schedule 650 is built and/or modified, a controlsignal 660 is generated by the control module 610 based on theprogrammable schedule 650.

FIGS. 7A-C are flow diagrams of another illustrative HVAC interviewprogram 700. The flow diagram starts at a normal thermostat operationblock 710, but this is not required in all embodiments. In theillustrative embodiment, the interview program 700 can be initiated bypressing a program initiation button or key such as, for example, an “EZSchedule” button.

The program can begin by asking whether the user wants the same scheduleto be used for every day of the week, as shown at block 720. If the userresponds with a “YES” response, then the program can move to ask contextquestions for that group of days, as shown at block 725, which may setthe schedule for the week assuming the same schedule for every 24 hourperiod or day. If the user responds with a “NO” response, the programmay ask the user if the same schedule applies to both weekend days,Saturday and Sunday, as shown at block 730. If the user responds with a“YES” response, then the program can ask if the user wants twoschedules, one for weekdays and one for weekends, as shown at block 735.A “YES response to block 735 can move the program to asking contextquestions for a weekend group of days and a weekdays group of days, asshown at block 725, to set the schedule for the week assuming a firstschedule for weekend days and a second schedule for weekdays. A “NO”response to block 730 can cause the program to ask whether the userwants three schedules including a weekday schedule, a Saturday schedule,and a Sunday schedule, as shown at block 740. A “YES” response to block740 moves the program to asking context questions for a week day groupof days schedule, a Saturday schedule and a Sunday schedule, as shown atblock 725, to set the schedule for the week assuming a first schedulefor weekdays, and a second schedule for Saturday and a third schedulefor Sundays. A “NO” response to either block 740 or block 735 moves theprogram to asking the user to group each day of the seven days of theweek into similar schedule groupings until all days are assigned to onegroup, as shown at block 750. The program can ask if all days areassigned at block 755, with a “NO” response returning the user to block750 to assign a non-assigned day or days until all days have beenassigned. Once all days have been assigned to a group, the program movesto asking context questions for each group of days schedule, as shown atblock 725, to set the schedule for the each grouping of days assuming afirst schedule for a first group, a second schedule for a second group,a third schedule for a third group and so on until all groupings of daysare scheduled.

The program 700 can ask a variety of context sensitive question todetermine the desired schedule for each grouping of days identified bythe program 700 above. For example, and as shown in FIG. 7B, the program700 can inquire whether someone is home all day, as shown at block 760.If the user enters a “YES” response to block 760, the program can askwhen the first person gets and request that the user to enter a waketime, as shown at block 770. Then the program 700 can ask when the lastperson goes to sleep and request that the user to enter a sleep time, asshown at block 780. If the user enters a “NO” response to block 760, theprogram can ask when the first person gets up, and request that the userto enter a wake time, as shown at block 761. Then the program can askwhat time the first person leaves home and request that the user enter aleave time, as shown at block 762. The program can also ask when thelast person gets home for the day, and request the user to enter areturn time, as shown at block 763. The program can also ask when thelast person goes to sleep, and request that the user enter a sleep time,as shown at block 764. Once all the above information has been enteredby the user for each grouping of days, the program may move to an endblock 781.

The program 700 can then request information from the user regardingcomfortable awake, sleeping and away temperatures. For example, andreferring to FIG. 7C, the program can request that the user enter acomfortable temperature when the heat is on, as shown at block 790. Thetemperature information received in block 790 can be automaticallyinserted into a program schedule for each grouping of days to set thewake heat and return heat set points. The program can also request thatthe user enter a comfortable temperature when the air conditioning ison, as shown at block 791. This information can be automaticallyinserted into a program schedule for each grouping of days to set thewake cool and return cool set points. This illustrative program can alsorequest that the user enter a comfortable summer sleeping temperature,as shown at block 792. This information can be automatically insertedinto a program schedule for each grouping of days to set the sleep coolset point. The program can also request that the user enter acomfortable winter sleeping temperature, as shown at block 793. Thisinformation can be automatically inserted into a program schedule foreach grouping of days to set the sleep heat set point. The program canalso request that the user to enter an energy savings offset at block794. This information can be automatically inserted into a programschedule for each grouping of days to set the leave cool and leave heatset points.

In some embodiments, the program 700 can allow the user to request aschedule review at block 795, which can allow the user to review thebuilt or modified schedule, as shown at block 796. If the user does notwish to review the schedule or when the user is done reviewing theschedule, the program returns to normal thermostat operation block 710under the newly built or modified schedule.

Referring now to FIG. 9, a block diagram of an illustrative HVAC systemincluding a programmable controller having interview capabilities forconfiguring one or more HVAC components will now be described. The HVACsystem 900 can include a programmable controller 902 in communicationwith a number of system components that can be activated to regulatevarious environmental conditions such as temperature, humidity, and airquality levels occurring within the space to be controlled. As shown inFIG. 9, for example, the controller 902 can be connected to a heatingunit 904 and cooling unit 906 that can be activated to regulatetemperature. The heating unit 904 can include a boiler, furnace, heatpump, electric heater, and/or other suitable heating device. In someembodiments, the heating unit 904 can include a multistage device suchas a multistage heat pump, the various stages of which can be controlledby the controller 902. The cooling unit 906 can include anair-conditioner, heat pump, chiller, and/or other suitable coolingdevice which can likewise be either single staged or multistageddepending on the application.

A ventilation unit 908 such as a fan or blower equipped with one or moredampers can be employed to regulate the volume of air delivered tovarious locations within the controlled space. A filtration unit 910, UVlamp unit 912, humidifier unit 914, and dehumidifier unit 916 can alsobe provided in some embodiments to regulate the air quality and moisturelevels within the controlled space. One or more local and/or remotesensors 918 can be connected to the controller 902 to monitortemperature or humidity levels inside, and in some cases, outside of thespace to be controlled. In some embodiments, the controller 902 can beconnected to one or more other controllers 920 such as another HVACcontroller for providing multi-zoned climate control. The systemcomponents can be directly connected to a corresponding I/O port or I/Opins on the controller 902, and/or can be connected to the controller902 via a network or the like.

The controller 902 can include a user interface 922 to permit aninstaller or service technician to input commands for programming thecontroller 902 to operate with the various system components and anyother connected controllers 922. The user interface 922 can include, forexample, a touch screen, liquid crystal display (LCD) or dot matrixdisplay, an aural interface including a speaker and microphone, acomputer, or any other suitable device for sending and receiving signalsto and from the controller 902. Depending on the configuration, the userinterface 922 can also include buttons, knobs, slides, a keypad, orother suitable selector means for inputting commands into the controller902.

FIG. 10 is a block diagram showing the controller 902 and user interface922 of FIG. 9 in greater detail. As can be further seen in FIG. 10, thecontroller 902 can include a control module 924 such as amicroprocessor/CPU, a storage memory 926, a clock 928, and an I/Ointerface 930 that connects the controller 902 to the various systemcomponents in FIG. 9. An internal sensor 932 located within thecontroller housing can be used to measure the temperature, humiditylevels, and/or other environmental conditions occurring within thecontrolled space.

During installation, the control module 924 communicates with the userinterface 922 to provide the installer with interview questions relatingto the configuration of one or more of the system components. In theillustrative embodiment of FIG. 10, the controller 902 includes aninterview question generator 934 that prompts the installer to providefeedback to the controller 902 regarding the types of system componentsto be controlled, the dates and times such components are to beoperated, the power or temperature levels in which such components areto be operated, the bandwidth or offsets at which such components are tobe operated, the type of space to be controlled, as well as otheroperating parameters. Activation of the interview question generator 934can occur, for example, by pressing an installation button on atouchscreen or keypad of the user interface 922. Alternatively, or inaddition, the controller 902 may activate the interview questiongenerator 934 on its own when a new system component is connected to theI/O interface 930 or when additional setup information is needed ordesired by the controller 902.

Input commands received via the user interface 922 can be fed to aresponse acceptor 936, which accepts the user responses to the interviewquestions generated by the interview question generator 934. Theresponse acceptor 936 can be configured to translate the user responsesinto operation parameters 938 that can be stored within the memory unit926 along with other information such as prior usage, schedulingparameters, user preferences, etc. The operation parameters 938 can thenbe used by the controller 902 to generate control signals 940 to operatethe various system components in a particular manner.

FIG. 11 is a flow chart showing several illustrative interview questionsand answers that can be provided by the interview question generator ofFIG. 10. As shown in FIG. 11, once the installation mode has beeninitiated, the user interface can be configured to prompt the installerto enter a desired language in which to display the interview questionand answer queries, as indicated generally by block 1000. For example,the user interface may prompt the installer to select between “English”,“Espanol”, or “Francais” as language choices. The selection of aparticular language at block 1000 causes the user interface tosubsequently display the interview questions and answers in thatselected language.

Once the desired language is chosen, the user interface can beconfigured to provide interview questions pertaining to the varioussystem components to be installed. At block 1002, for example, the userinterface can prompt the installer to select the type of equipment to becontrolled by the controller. In certain embodiments, for example, theuser interface can prompt the installer to select between a conventionalheating/cooling unit, a heat pump, or heat only. Once the type ofequipment has been selected, the user interface may then prompt theinstaller to enter the number of stages of heat and cool to becontrolled by the controller, as indicated generally by blocks 1004 and1006. In some embodiments, the answers provided to the interviewquestion at block 1004 may affect whether the user interface displays afollow-up query at block 1006. For example, if the response to theinterview question regarding the number of heat stages at block 1004 is“2”, the interview question generator may assume that there are 2cooling stages, and thus skip the query at block 1006.

For each stage of heat and cool, the user interface can be configured toprompt the installer to select the number of cycles per hour to beprovided by the equipment, as indicated generally by block 1008 and1010, respectively. At block 1008, for example, the user interface mayprompt the installer to select the cycles per hour to be provided byeach stage of heating selected at block 1004. If, for example, theinstaller indicates at block 1004 that the equipment has 3 stages ofheating, the user interface can be configured to repeat query block 1008three separate times for each individual stage to be configured. Asimilar process can then be performed at block 1010 for each stage ofcooling to be controlled by the controller. If at block 1004 theinstaller indicates that there are “0” stages of heat, the userinterface can be configured to skip the query at block 1008. Inaddition, if at block 1006 the installer indicates that there are “0”stages of cool, or if at block 1002 the installer indicates that theequipment is “Heat Only”, the user interface can be configured to skipthe query at block 1010.

In some embodiments, the user interface can be further configured toprovide the installer with interview questions and answers that can beused to set other operational parameters within the controller. Asindicated generally at block 1012, for example, the user interface canbe configured to prompt the installer to select the minimum amount of ontime that the equipment operates. The user interface can further promptthe installer to select a lower and/or upper temperature limit at whichthe system operates, as indicated generally at blocks 1014 and 1016,respectively. If desired, the temperature offset and proportionalbandwidth of the system can be further set via query blocks 1018 and1020, respectively.

Although several exemplary interview questions and answers areillustrated in FIG. 11, it should be understood that the type, number,and ordering of the interview questions and answers provided to theinstaller may be varied based on the type of equipment to be configured,the user's previous answers to interview questions, the number of stagesto be controlled, as well as other factors. In some embodiments, theinterview questions and answers can be grouped together to permit theinstaller to configure a particular system component or componentswithout having to answer interview questions for the remaining systemcomponents. If, for example, the installer desires to only configure anewly installed heat pump, the user interface can be configured toprovide the installer with interview questions and answers relating tothe cooling unit, skipping those queries related to other components notaffected by the installation.

FIG. 12 is a flow diagram of an illustrative method 1100 of programmingconfiguration information within a controller. The method 1100 can begingenerally at block 1102 in which an installation mode of the controlleris activated to permit an installer to configure the controller tooperate with one or more system components. Initiation of theinstallation mode can occur, for example, by the installer selecting aninstallation mode button on a touchscreen or keypad of the userinterface, or automatically when the controller is activated for thefirst time or when one or more system components are connected to thecontroller.

Once the installation mode has been initiated, the controller can thenbe configured to provide one or more interview questions to theinstaller via the user interface, as indicated generally by block 1104.The interview questions provided can be configured to solicitinformation from the installer regarding the type and configuration ofthe various system components to be controlled by the controller. Incertain embodiments, for example, the interview questions can include asequence of interview questions relating to the type of equipment to becontrolled, the number of heat stages the equipment has, the number ofcooling stages the equipment has, the number of cycles per hour eachstage of heating requires, and the number of cycles per hour each stageof cooling requires.

In some embodiments, other interview questions pertaining to the type orconfiguration of the controller and/or any system components controlledby the controller can be further presented to the installer via the userinterface. Examples of other interview questions can include, but arenot limited to, the minimum operating time desired to operate thesystem, whether a pump exercise is to be enabled for any installed heatpumps, the upper temperature limit at which to operate the system, thelower temperature limit at which to operate the system, the temperatureoffset at which the controller operates, the proportional bandwidth ofthe equipment, the type and operating times of the ventilation fanemployed, the type and rating of the UV lamp employed, and the type andrating of the humidifier or dehumidifier employed. Other interviewquestions relating to the user's preferences such as the date and timeformat, daylight savings options, schedule programming options,temperature display options, etc. can also be provided, if desired. Itshould be understood that the types of interview questions and theirordering will vary depending on the type of equipment to be controlled.

The interview questions may be provided to the installer in the form ofnatural language questions, which may be phrases having one or morewords that prompt the installer to select between one or more answersfrom a predetermined list of answers. For example, the interviewquestions can include a question such as “What type of equipment is thethermostat controlling?” In some embodiments, one or more of theinterview questions may elicit an affirmative “YES” or “NO” userresponse. Alternatively, or in addition, one or more of the interviewquestions can solicit information requiring a numeric or alphanumericuser response.

With certain interview questions, and in some embodiments, thecontroller can be configured to prompt the installer to select betweenat least two answers or responses displayed on the display screen of theuser interface, as indicated generally by block 1106. For example, inresponse to the interview question “What type of equipment is thethermostat controlling?”, the user interface can be configured todisplay the answers “Conventional”, “Heat Pump”, and “Heat Only”,prompting the installer to select the appropriate type of equipment tobe installed and/or configured. The user interface can then beconfigured to accept the user responses to each of the questions andthen modify the operational parameters of the controller based on theuser responses, as indicated generally by blocks 1108 and 1110,respectively.

In some embodiments, the user interface can be configured to displayeach of the answers simultaneously on the display screen of the userinterface. In such configuration, the selection of a user response atblock 1108 can be accomplished by the installer selecting an answer tothe interview question from a list of multiple answers graphicallydisplayed on the screen. In those embodiments in which the userinterface includes a touchscreen, for example, the selection of aresponse can be accomplished directly by pressing the desired answerfrom a choice of answers provided on the screen, causing the controllerto store that parameter and cycle to the next interview question in thequeue. Alternatively, in those embodiments in which the user interfaceincludes an LCD or dot matrix screen, the selection of the desiredanswer from the choice of answers can be accomplished via a button,knob, slide, keypad, or other suitable selector means on the userinterface.

The user interface can vary the presentation of the interview questionsbased at least in part on the installer's previous responses to otherinterview questions. If, for example, the installer selects on the userinterface that the type equipment being installed is “Heat Only”, theinterview question generator can be configured to skip those questionspertaining to the stages and cycle times for cooling. The ordering ofthe interview questions can also be varied based on the particular pieceof equipment being configured. If, for example, the installation mode atblock 1102 is initiated in response to a new piece of equipmentconnected to the controller, the interview question generator can beconfigured to present to the installer only those questions pertainingto the new equipment.

The interview question generator can also be configured to suggest adefault answer based on any previous responses, based on any previouscontroller settings, and/or based on settings which are commonlyselected for that particular piece of equipment. For example, withrespect to the selection of the number of stages for heating, the userinterface can be configured to default to a common answer or response of“2” while providing the installer with the ability to select among othernumbers of heating stages (e.g., “0”, “1”, “3”, “4”, “5”, “6”, etc.), ifdesired. The suggestion of a default answer can be accomplished, forexample, by highlighting or flashing the answer on the display screen,by moving a selection indicator adjacent to the answer on the displayscreen, or by other suitable means.

FIGS. 13A-13Z are schematic drawings of an illustrative HVAC touchscreeninterface 1200 showing an illustrative implementation of the flowdiagram depicted in FIG. 12. In a first view depicted in FIG. 13A, theinterface 1200 can be configured to display a main installation menuscreen 1202 on the display panel 1204, providing the installer with thechoice of configuring one or more HVAC system components. The maininstallation menu screen 1202 can include, for example, a “FULL SET-UP”icon button 1206, a “COMPONENT BASED SET-UP” icon button 1208, and a“MANUAL SET-UP” icon button 1210.

The “FULL SET-UP” icon button 1206 can be selected on the display panel1204 to permit the installer to fully configure the controller to workwith the system components for the first time, or when the installerotherwise desires to cycle through each of the interview questions insequence. The “COMPONENT BASED SET-UP” icon button 1208, in turn, can beselected to permit the installer to configure only certain systemcomponents or to configure the system in a different order than thatnormally provided by the interface 1200. The “MANUAL SET-UP” icon button1210 can be selected to permit the installer to configure the controllermanually using numeric or alphanumeric codes, if desired.

FIG. 13B is a schematic drawing showing the selection of the “FULLSET-UP” icon button 1206 on the main installation menu screen 1202 ofFIG. 13A. As shown in FIG. 13B, the selection of icon button 1206 causesthe interface 1200 to display a language setup screen 1212 that promptsthe installer to select a desired language format for the remainder ofthe installation configuration. The interface 1200 can be configured todisplay, for example, an “ENGLISH” icon button 1214, an “ESPANOL” iconbutton 1216, and a “FRANCAIS” icon button 1218. Other language choicescan also be displayed on the language setup screen 1212, if desired. A“BACK” icon button 1220 and “ENTER” icon button 1222 can be provided onthe display panel 1204 to permit the installer to move back to the priorscreen or to enter the current setting selected and move forward to thenext question in the queue. A “QUIT” icon button 1224 can be provided onthe display panel 1204 to permit the installer to quit the installationconfiguration mode, save any changes made, and then return thecontroller to normal operation.

FIG. 13C is a schematic view showing the interface 1200 after theselection of the “ENGLISH” icon button 1214 on the language setup screen1212 of FIG. 13B. As shown in FIG. 13C, once the installer has selecteda desired language, the interface 1200 can be configured to display anequipment type screen 1226 allowing the installer to select the type ofequipment to be configured. In some embodiments, for example, theequipment type screen 1226 may prompt the installer to select among a“CONVENTIONAL” icon button 1228, a “HEAT PUMP” icon button 1230, or a“HEAT ONLY” icon button 1232 each simultaneously displayed on thedisplay panel 1204.

Once the installer has selected the desired equipment to be installedvia the equipment type screen 1226, and as further shown in FIG. 13D,the interface 1200 can be configured to display a screen 1236 promptingthe installer to select the number of heat stages to be configured, ifany. Several numeric icon buttons 1238 can be provided on the screen1236 to permit the installer to select the desired number of heat stagesto be controlled. If, for example, the equipment to be configured has 2stages of heating, the installer may select a “2” icon button 1238 a onthe screen 1236. Conversely, if the equipment to be configured has noheating stages, the installer may select a “0” icon button 238 b on thedisplay screen 1236, causing the interface 1200 to thereafter skip thoseinterview questions pertaining to heating stages and cycles.

Once the number of heat stages has been configured via screen 1236, andas further shown in FIG. 13E, the interface 1200 can be configured todisplay another screen 1240 prompting the installer to select the numberof cooling stages to be configured, if any. Several numeric icon buttons1242 can be provided simultaneously on the screen 1240 to permit theinstaller to select the desired number of cooling stages. If, forexample, the equipment to be configured has 2 stages of cooling, theinstaller may select a “2” icon button 1242 a on the screen 1240.Depending on the response to the previous interview question on screen1236 of FIG. 13D, the interface 1200 can be configured to default to aparticular answer (e.g. “2”) by blinking or flashing the answer on thescreen 1240. In some cases, the interface 1240 may assume that thenumber of cooling stages is the same as the number of heating stages andskip screen 1240 altogether.

FIG. 13F is a schematic view showing the interface 1200 subsequent tothe steps of configuring the heating and cooling stages in FIGS.13D-13E. As shown in FIG. 13F, the interface 1200 can be configured toprovide a screen 1244 initially prompting the installer to select adesired number of cycles per hour for the first stage of heating.Several numeric icon buttons 1246 can be provided simultaneously on thescreen 1244 to permit the user to select the cycle rate at which thesystem operates for the particular stage number 1248 displayed on thescreen 1244. For the first stage of heating for a two-stage system, forexample, the installer may select the “6” icon button 1246 a to operatethe first heating stage for six cycles per each hour. Once a response isreceived for the first heating cycle, the interface 1200 may then promptthe installer to select the number of cycles for the second heatingstage, as further shown in FIG. 13G. The process can be repeated one ormore times depending on the number of heating stages to be configured.

FIG. 13H is a schematic view showing the presentation of another screen1250 on the interface 1200 for selecting the cycle rate for each coolingstage to be configured within the controller. Similar to the screen 1244depicted in FIGS. 13F-13G, the screen 1250 may prompt the installer toinitially select a desired number of cycles per hour for the first stageof cooling, and then repeat the interview process for each additionalstage to be programmed, if any. Several numeric icon buttons 1252 can beprovided simultaneously on the screen 1250 to permit the installer toselect the cycle rate at which the system operates for the particularstage number 1254 displayed on the screen 1250. Once the installer hascompleted configuring each stage of heating and cooling, the interface1200 can be configured jump to additional interview questions for anyother components to be configured, or, alternatively, can exit theroutine and return to normal operation using the newly programmedsettings.

Once programming is complete, and as further shown in FIG. 13I, theinterface 1200 can be configured to display a screen 1256 indicatingthat the configuration was successful along with a “VIEW SETTINGS” iconbutton 1258 allowing the installer to view the controller settings. A“BACK” icon button 1260 can be selected if the installer desires to goback and modify or change any settings. A “DONE” icon button 1262, inturn, can be selected by the installer to return the controller tonormal operation.

Referring back to FIG. 13A, if the installer desires to configure onlyselective components of the system, or prefers to enter configurationinformation in an order different than that generated by the interviewquestion generator, the installer may select the “COMPONENT BASEDSET-UP” icon button 1208 on the main installation menu screen 1202. Whenselected, the interface 1200 can be configured to display a componentselection screen 1264, allowing the installer to select from amongseveral different categories of equipment for configuration, as shown inFIG. 13J. The component selection screen 1264 can include, for example,a “HEATING” icon button 1266, a “COOLING” icon button 1268, a“VENTILATION” icon button 1270, a “FILTRATION” icon button 1272, a “UVLAMP” icon button 1274, a “HUMIDIFICATION” icon button 1276, and a“DEHUMIDIFICATION” icon button 1278. The icon buttons can correspond,for example, to the system components described above with respect toFIG. 9, although other combinations of system components arecontemplated. An “OTHER” icon button 1280 provided on the screen 1264can be selected by the installer to configure other system componentssuch as any sensors or other connected controllers, if desired.

The selection of the icon buttons on the component selection screen 1264causes the interface 1200 to display one or more interview questions andanswers on the display panel 1204 based on the type of equipment to beconfigured. If, for example, the installer desires to configure only theheating and cooling system components, the installer may select both the“HEATING” icon button 1266 and “COOLING” icon button 1268 on the screen1264, causing the user interface 1200 to present only those interviewquestions that pertain to heating and cooling control.
